OC a laptop

[shovenose]

I have an hp pavilion dv4-1145go laptop. 4gigs ram, 2ghz c2d cpu, and lousy graphics. anyway, can i OC the processor, how high can i go, and will it actually make it faster? can i oc the graphics?
i also have a very stupid question: can i overclock the hard drive?
thanks isn advance

1.Use FSB to overclock the CPU.

2. Depending on the graphics you may be able to use evga precision.

3. The speed you are able to achive really depends on the chip you have.

4. No you cant OC a HDD. YOu should be able to overclock an SDD though.

i have an intel graphics, so can i use evga precioson

I dont think you can oc a manufactured computer(unless it's super high end). u might be able to oc the graphics using software but i doubt cpu is ocable

no...

Also OCing a laptop is usually asking for trouble, unless you have upgraded the cooler for it. Some manufacturers use a heatsink and fan that could cool the chips just a bit below the maximum temps intel or amd suggests.

^ yeah, agreed. Really dangerous.

I recently disassembled a dead toshiba laptop and noticed they used some sort of rubber-like thermal pads instead of paste. While the ones on gfx chip and mosfets were still fine the one on cpu(c2d @ stock 1.66ghz) has totally disintegrated and there was no contact between the core and the heatsink anymore, and this laptop was less than 18 months old. Go figure

Yea don't even try it, you are prone to overheat the CPU just by raising the clock a few hundred MHZ and that is IF you are able to unlock the bios.... The only laptop that I was able to overclock w/o any issues was an alienware m17 that had good CPU cooling. I was only able to ge an extra 400Mhz and CPU temps were around the high 60's....

If you use a third party software you are wasting your time =)

Don't do it. If you have to ask how to do it, you probably shouldn't do it.

Overclocking a laptop can be rather troublesome. You can probably get away with a mild FSB overclock using simple software overclocking, but you have to understand that the cooling on your laptop is only designed to handle a specific amount of heat. The dynamic power saving technologies will have trouble if they try to lower the core speed and voltage only to find the FSB you selected requires a little more juice.

ok

AFAIK the DV4 doesn't support BIOS overclocking and if I'm not mistaken the mainboard uses a PLL which isn't software overclockable so you would possibly have to do something like this.

Don't expect to be blown away by the results of overclocking 25% though.

ok thanks
but im not doing that, too many things could go wrong

Exactly ^^ ........
